Abstract: An adaptive clock recovery arrangement for deriving a synchronous clock from an asynchronous, packet stream such as an asynchronous transfer mode (ATM) cell stream. The deviation in the magnitude of information stored in a first-in-first-out memory is continually monitored, and the synchronous clock frequency, referred to as the adaptive line clock frequency, is adjusted in a plurality of modes, under the control of a processor. The adjustment is made in response to a detected increasing condition of the monitored deviation. The adjustment are open-loop adjustment made without continually adjusting the adaptive line clock frequency based on the monitored deviation. Damping is substantially reduced compared with"conventional" PLL arrangements because the open-loop adjustments result in a rapid frequency correction with perfect or nearly perfect deadbeat damping, i.e.without the frequency oscillations that continue after the correct frequency is reached in closed-loop arrangements.

Abstract: The present invention provides a wash arm for a dishwasher which includes first and second openings which simultaneously propel the wash arm and rinse or back-flush filtered debris from a filter. The filter includes a settling chamber and a mesh screen, the mesh screen defining a portion of the top surface of the settling chamber and including inner and outer surfaces. Wash water flows through the mesh screen from the inner surface to the outer surface, causing filtered debris to be retained or trapped on the inner surface of the filter . The openings in the wash arm are downwardly and outwardly directed, and supply rinsing jets of wash water which impinge upon the outer surface of the filter and rinse retained debris from the inner surface thereof. The rinsed debris is thereafter held and suspended within the settling chamber until the dishwasher is drained. The pair of openings are radially displaced first and second distances from a center of the wash arm. Reaction forces produced by water exiting the openings combine or cooperate, resulting in a net reaction force which rotatably drives the wash arm about its axis of rotation at a predetermined rate.

Filed: 1994-06-09
Abstract: ABSTRACT An input auxiliary transmission system is disclosed for a compound transmission (15) comprising an auxiliary transmission section (17) in series with a change gear mechanical main transmission section 19. The auxiliary section includes an input splitter (41) including first (53,47) and second (53,49) jaw clutches. When each of the jaw clutches is disengaged, the splitter is in a third position in which the input shaft (13) is disengaged from the auxiliary section output gear (45). The invention provides a fluid pressure actuator (61) having athird position operable to move the jaw clutch to the disengaged condition. The transmission includes means (121) to sense the shift mechanism (21) of the main section being in a neutral condition, and valve means (89) which communicates pressurized fluid to the actuator (61) to move it to its third position, thus eliminating a major portion of the inertia as the main transmission section 19 passes through neutral prior to making a gear shift. As a result, it is possible for the synchronizers in the main section to be much smaller and less expensive.

Title: Methods and apparatus for retiming and realignment of sts-1 signals into sts-3 type signal
Inventor: PARRUCK BIDYUT
IPC: H04L25/05
Filed: 1993-03-09
Abstract: The SPE of an incoming STS-3 type signal is demultiplexed into three STS-1 payloads and fed to three FIFOs (45-1, 45-2, 45-3), and a byte which is synchronous with the TOH is tracked through the three FIFOs (45-1, 45-2, 45-3) to provide an indica-tion of the FIFO depth. A frame count is also kept to track the number of frames since a last pointer movement. Stuffs or destuffs are generated based on the FIFO depth as well as based on the frame count, with a stuff or destuff generated as quickly as four frames from a previous pointer movement if the FIFO is close to full or close to empty, and less quickly (e.g., at thirty-two frames from a previous pointer movement) if the FIFO is only starting to empty or to fill. Where the STS-3 type signal is an STS-3C sig-nal, the decision on whether to stuff or destuff is made with reference to all three depth measurement circuits (48-1, 48.2, 48-3) as all the STS-1 payloads must be stuffed or destuffed together.

Title: Regulation method for a dc arc furnace
Inventor: GAUPP OSVIN
IPC: C21C5/52
Filed: 1994-11-23
Abstract: In  operation,  DC  arc  furnaces  (8)  produce reactive load fluctuations which lead to undesirable flickering phenomena especially in a frequency range from 2 Hz - 20 Hz.  In order to reduce these flickering phenomena, comparatively fast reactive power regulation is superimposed on slow current regulation of the DC arc furnace (8) which is controlled by rectifiers (5, 5').    In  consequence,  the  use  of  a  reactive-power compensator   to   compensate for   reactive   power fluctuations is superfluous.

Title: Detection of Nucleic Acid Amplification
Inventor: NADEAU JAMES G
IPC: C12N15/09
Filed: 1995-03-28
Abstract: Fluorescence polarization methods for detection of nucleic acid amplification. Afluorescently labelled oligodeoxynucleotide probe is converted from single- to double-stranded form in a target dependent manner during amplification of the target sequence. This conformational change is accompanied by an increase in fluorescence polarization values. The increase in fluorescence polarization can be measured on a transient-state fluorometer in real-time during the amplification reaction without any physical manipulation of the sample. The inventive methods therefore provide a closed, homogeneous system for both amplification of target sequences and detection of amplification. Alternatively, amplification may be detected in the fluorometer after the amplification reaction is completed.
